Drew Peterson Called In Sick on Night of Wife's Disappearance

The husband of Stacy Peterson did not show up to work on the night that the 23-year-old woman disappeared, FOX News confirmed Wednesday.

Stacy Peterson, a mother of two and Drew Peterson's fourth wife, was reported missing Oct. 29 by her family after she failed to show up to a friend's house.

Drew Peterson, who recently resigned as an officer from the Bolingbrook police department, was scheduled to work at 5 p.m. Oct. 28 but called in to take a personal or sick day, Bolingbrook police Lt. Ken Teppel told FOX News.

"Peterson called in sick for Sunday night (Oct. 28)," Teppel said. "The call was taken by a dispatcher in the afternoon."

A key witness has told a friend he might have helped transport the body of Peterson's wife, according to a Chicago Tribune report. That witness — a relative to Drew Peterson — allegedly helped move a barrel that was warm to the touch from Peterson's bedroom to an SUV. A source close to the investigation says that witness told a friend about his involvement.

Two days later, the distressed relative, who has not been identified, was hospitalized after an alleged suicide attempt, the Tribune reported.

Volunteers searching for any signs of Stacy are looking for the barrel. Neighbors say Peterson had a blue barrel in his backyard.

Peterson's neighbor told police last week that he saw Peterson and the man load a barrel "big enough to put someone in" into the former police officer's SUV, according to a Chicago Sun-Times report.

The Wednesday after Stacy disappeared, Drew Peterson asked his next-door neighbor to watch the kids after his step brother-in-law tried to commit suicide. Peterson told the neighbor, Sharon Bychowski to watch two of Peterson's kids for an hour.

Bychowski, one of Stacy's best friends, told FOX News that Peterson had a lack of emotion and dismissive attitude when he returned from the hospital to pick up the kids. Bychowski asked Peterson if everything was okay and he responded, "What? Oh. He lost his job. Lost his family. Go figure."

Peterson also asked Bychowski to move Stacy Peterson's Grand Prix, which has since been seized by investigators, to keep it away from the media.

Peterson's attorney is denying reports about a family member helping the former police officer remove a blue barrel from his home after Stacy Peterson was reported missing.

Joel Brodsky, Peterson's attorney, said the family member has a history of mental problems, alcoholism and suicide attempts. The family member might want attention or living in "a fantasy world," Brodsky said.

Meanwhile, Will County prosecutors reopened the investigation into the death of Peterson's third ex-wife, Kathleen Savio. Savio, 40, died in a bathtub in March 2004. Prosecutors say the death appeared to be staged to conceal a homicide and recently exhumed her body for a second autopsy.

Illinois State Police told FOX News on Sunday that "new information" prompted its appeal for more information about possible sightings of the cars that belong to Stacy Peterson or her husband, Drew, around the time that the woman vanished.

Police have released photos of the vehicles: A dark Blue 2005 GMC Yukon Denali belonging to Drew and the second a purple 2002 Pontiac Grand Am, belonging to Stacy, and asked the public to call its tip line at 815-740-0678 or "America's Most Wanted" at 800-274-6388.

Both vehicles were impounded by police on Nov. 1 and are still in police possession.
